Along a coastline armored with groynes, which outcome results from the disruption of longshore drift?

💡 Explanation

Down-drift erosion intensifies because groynes interrupt longshore drift, the transport of sediment along the coast; therefore, areas downstream from groynes experience sediment starvation and increased erosion, rather than sediment accumulation or changed estuary conditions.
